About This Product
The Rheem 9.5 GPM Performance Platinum Super High Efficiency Indoor Natural Gas Smart Tankless Water Heater delivers more hot water than most tank water heaters. The 199,900 BTU Super High Efficiency Natural Gas Tankless Water Heater can provide enough on demand hot water to supply up to 3 bathrooms at the same time (at a 35° water temperature increase). It's also more efficient than most traditional tanks; it's up to 52% more efficient than a standard 50-gallon gas tank water heater. This model has a 0.93 Uniform Energy Factor (UEF), which means it may qualify for local utility rebates and incentives. Plus, this is a smart tankless model; built-in Wi-Fi Technology provides valuable alerts and control from anywhere with a smart phone. The Platinum's venting allows for it to be installed in many locations and it uses PVC for venting enabling an easier installation and reduced installation time; easier installs are just one of the reasons Rheem Tankless Hot Water Heaters are preferred by contractors. This is a natural gas model.

Questions & Answers
Is this are quick flush, condensed, has a circular pump system
I have Rheem serial number w401805845 is this a replacement for the unit
Hi Antonette, Based on the information provided, the Performance Platinum ECOH200DVELN-3 can replace your old RTG-70DVLN-1, but you cannot reuse the existing venting system. While both are indoor, natural gas units with matching plumbing lines, they use entirely different internal combustion technologies. Replacing your old RTG-70DVLN-1 with the new ECOH200DVELN-3 requires three mandatory infrastructure updates: • New PVC Venting: You must fully remove the old 3"/5" concentric metal vent. The new condensing unit requires Schedule 40 PVC or CPVC pipe (2-inch or 3-inch). • Condensate Drain Line: The new heater extracts extra heat from exhaust, producing water byproduct. You must route a new drain tube from the base of the cabinet to a nearby drain or pump. • Gas & Plumbing Alignment: The water and gas line connections remain the same size (3/4-inch NPT), though the new unit delivers a higher heat output capacity (199,900 BTU vs. 160,000 BTU), which may require your plumber to verify the existing gas pipe length and volume. For additional assistance, please call 866-279-4566 between the hours of 7 A.M. and 7 P.M. CST. Derius

Is this unit all stainless steel
Hi Mark, No, the Performance Platinum 8.4 GPM tankless water heater is not all stainless steel. For additional information assistance, please call 866-279-4566 between the hours of 7 A.M. and 7 P.M. CST. Derius
What is the exhaust pipes with? PVC? And is it convertible to propane!
Hi, Based on the information provided, you can use PVC exhaust pipes with this model, but it is not allowed to be field-converted to propane. If you require a liquid propane (LP) unit, you must specifically buy the propane version instead of trying to alter the natural gas model. The factory-configured Liquid Propane twin to this model features a slightly different model number string ending in "LP" rather than "LN". For additional assistance, please call 866-279-4566 between the hours of 7 A.M. and 7 P.M. CST. Derius
Can this change to.propane?
Hi Chris, Based on the information you provided, this specific model cannot be converted or changed to propane. The "N" at the end of the model number means it is factory-configured strictly for Natural Gas. The internal burner and gas manifold cannot be adjusted or field-converted to run on liquid propane (LP). For additional information, please call 866-279-4566 between the hours of 7 A.M. and 7 P.M. CST. Derius
What size long line
Hi Nick, Based on the information provided, if your gas run from the main meter is longer than 24 feet, or if your incoming gas pressure is lower than 7.0" w.c., you must run a 3/4-inch gas supply line. The physical connection port on the bottom of the heater itself is a 3/4-inch NPT connection. For additional assistance, please call 866-279-4566 between the hours of 7 A.M. and 7 P.M. CST. Derius
